Finger-hold for safety razors



Jufiy H, W330 w. W. ROBINSON FINGER HOLD FOR SAFETY RAZORS Filed Aug. '22, 1932 INVENTOR M41) Patented July 11, 1933 UNITED STATES WALLACE W. ROBINSON, OF IPORTLAND,.MA INE FINGER-HOLD Fon- SAFETY rnzons Application filed August 22, 1932. Serial No. 629,796.

My invention relates to improvements in safety razor holding devices and deals paricularly with the handle portion thereof, or the element on the device which is grasped by the'user in the operation of shaving.

A. razor equipped with the conventional type of straight handle is somewhat awkward to manipulate when shaving certain portions of the body.particularly so in connection with shaving the arm-pits and parts of the face along the neck line. p i

The primary object of the present invention is to sup 31v facilities in the handle porl l Fig. 8, 1t permits of slight variation in the tion of razor devices whereby the instrument may be more'firmly and conveniently held in the users hand while shaving, the structural improvement residing in the incorporation of a ring or band shape finger-hold by means of which therazor can be manipulated so that all the different strokes required inshaving the face or other parts of the body, can be made without changing or rearranging the three-point grasp which this particular form or shape cf holding element provides.

The grasp of the razor is made so effectively that even when the fingers have been smeared with soap or shaving cream the hold on the instrument is in no way afiected. Furthermore, the finger-hold can be positioned and secured on the guard element so that any one of various angles of presentment of the blade to the users face can be had, and after once being set in the desired position this relation can be more accurately maintained than is possible withthe ordinary round handle affair.

In the accompanying drawing I have disclosed certain embodiments of my invention which, at the present time, I consider preferable to other possible forms in which the invention might be carried out.

In the drawing,

Fig. 1 represents, in perspectiveview, a

razor being held by a device constructed in accordance with my invention; Y

Fig. 2 is a central, longitudinal section through the assembled parts;

Fig. 3 is a transverse section through the assembled parts, thefinger-hold element embodying a somewhat modified construction.

Like reference characters are used. to identify like parts; I! v Referring to the drawing, 1 is therazor guard, 2 is the razor blade, 3 the back member and 4 the screw, by which in conjunction with the nut 5 the parts are-secured together. he finger-hold 6 is madeiin the form of a band which can be constructed from a tube or made of flat material and bent into circular shape.

If the free at. are as disjoined, as in size of the band by spreading the legs of the band to fit any particular size of finger.

The band has a hole 7 in its wall to receive the screw 4, and the nut 5 impinging on the inside surface'of the band secures it in position on the guard. r

In the Fig. 2 illustration the band 6, adj acentthe hole 7, makes a tangential contact with the face of the guard, and the edges of the nut 5 bearing on the inside of the band, outwardly of the hole, effects a somewhat yielding engagement ofthe band with the guard.

The nut 5 has an enlarged head of sufli cient diameter to facilitate grasping itbetween the thumb and fore finger to tighten :8

or loosen it. 7

The outward pressure of the blade when flexed by the back member 3 also serves to provide a yieldable binding together of the parts and permits of the finger-hold being placed at various angular positions, longitudinally or transversely of the guard, or angles therebetween. Fig. 2 shows the fingerhold disposed longitudinally of the blade and guard and Fig. 3 illustrates it at a right angle thereto-or in a transversely located position.

The finger-hold band 6 and the nut 5 may be made as detached units, as shown in Fig. 2 or they may be combined, as shown in Fig. 3, as non-detachable-one from the other, in which latter construction the hole 7 is made in an inwardly bumped portion 6a of the wall of the band to receive the reduced portion. 5?)

of the shank of the nut 5. The extreme end of the nut shank, at 50 is headed over; thus the nut may revolve in the hole 7 but cannot be disengaged from the band. This eliminates the possibility of losing the nut when the parts are disassembled for cleaning and drying. V

The depression in the bumped portion 6a is made sufiiciently deep to prevent contact of the end of the shank of the nut with the razor guard 1 and permits the band to be drawn tightly on to the guard and frictionally held thereon under whatever yieldability the bumped portion affords.

I may elect to perforate the wall of the band with holes 8, making the gripping quality of the finger-hold somewhat augmented by reason of the fact that the flesh of the fingers and thumb will protrude into the holes and provide resistance-toslipping of the hold ing element while being used.

When the finger-holdis disposed on the guard as shown in Fig. 3 the center of gravity of the device is located at such a point that in whatever position it is laid on a flat surfaceexcept on its ends-it will roll into an upright position.

In re-arranging the finger-hold by unloosening the screw it necessarily disturbs the adjustment of the blade 2. g

The grasp of a shaving instrument equipped with my improved finger-hold attachment is much more natural, secure and convenient than is the case with the ordinary small round handle; it is cheaper to construct, can be packed into a smaller space and is considerably lighter in weight. The screwthread on the member 4 is made to conform to existing standards so that the long handle of the ordinary razor holder can easily be displaced by my outfit without other change or alteration of structure.

The embodiment above disclosed is of course primarily illustrative and my invention is, obviously, capable of interpretation in a wide Variety of structures.

What I'claim is:

1. A safety razor holding device comprising in combination with a guard, a back mem her and a screw-threaded stud extending from said back member to and through said guard, a finger-engaging band of generally circular form rotatively mounted on said guard, an inwardly disposed depression in the wall of said band, an aperture in the bottom of said depression, a nut, adaptable of screw-threaded engagement with said stud, disposed within said band, a reduced portion on said nut operable in said aperture, and means to hold said nut against displacement from said band when disengaged from said stud.

2. A safety razor comprising in combination with the guard, having a central hole therethrough, a back member, a razor blade interposed between the said guard and said back member, a threadedstud integral with said back member and extending therefrom to and through said guard, of a finger-engagingband,having a hole through its wall, disposed on and adaptedto thrust against said guard, a nut, having a reduced portion operable in said hole, adapted to engage said stud and thrust on the inside of said band, said nut adapted to secure said band in any one of a plurality of pie-determined angular positions on and with respect to said guard simultaneously with deflecting said blade to any desired degree, and means to hold said nut against displacement from said band.

In testimony whereof Iaffix my signature.
